In the never section deflections results there is a L/y Ratio & L/z Ratio. I see that in the Risa Help menu there is an arbitrary L/360 value for the example. What is the typical deflection criteria used & how does Risa flag these criteria?

The current version of RISA-3D only reports the member deflection ratio. It does not pass or fail them based on an L/360 (or any other ratio).

RISAFloor, on the other hand, does a lot with deflection ratios. But, because this was posted to the RISA-3D formum, I am assuming that you are not asking about that program at all.

Thanks, Yes I only use RISA3D not familiar with the other package you mentioned.
